完美解决ThinkPad Win7恢复盘所安装的系统弹出USB等反应慢的方法

相信各位使用过ThinkPad Win7恢复盘安装过系统的都有点很不爽的感觉，那就是“安全删除硬件及弹出媒体”时那龟速，打开“设备和打印机”时那龟速，打开任务栏那“来弄偶Link"时那龟速,实在是让大家受够了,今天把我的解决办法分享给大家,保证1.2秒内打开上述功能.
特别提示,
1、只适合用ThinkPad Win7恢复盘所安装的系统(不管是32位还是64位,也不管是什么语言的系统更不管是啥机型).
2、注意：确保“C:\ProgramData\Lenovo\LenovoTvtTools”下的文件都还在
新出的恢复盘包括64位的，似乎都没解决这问题
造成慢的原因在于Lenovo ThinkVantage Tools下的*.devicemetadata-ms文件与WIN7原有的文件有重复或冲突，该方法是将所有的*.devicemetadata-ms文件先删除，再重新导入Lenovo ThinkVantage Tools下的*.devicemetadata-ms文件，就可以解决这个问题
。如果“C:\ProgramData\Lenovo\LenovoTvtTools”下的文件有丢失的，转到C:\ProgramData\Microsoft\Windows\DeviceMetadataStore下各文件夹中把最大最新的devicemetadata-ms文件留着，别的都删除即可
如果“C:\ProgramData\Lenovo\LenovoTvtTools”下的文件还完整的将以下内容（蓝色部份）COPY到新建的文本文档然后另存为.bat 的文件运行即可，注销重登录后定生效（可上传的附件格式N少没办法，大家自己处理吧，好用记得顶贴）
